[toc position='left'] Aging refers to the collective physiological, functional, and mental changes that accrue in a biological organism over time. The hallmarks of aging are observable biological patterns of dysfunction that occur with aging. Integral to the aging process is inflammaging, the chronic, low-grade inflammation that occurs with aging.[ref doi='10.1111/j.1749-6632.2000.tb06651.x'] The mechanisms that drive inflammaging and the pathological conditions that arise because of it are bidirectional and involve multiple physiological processes and pathways, many of which directly or indir... mitochondria aging omega-3 stem cells aerobic senescence
Read more[toc position='left'] Thymic involution is the process by which the thymus shrinks with age and produces fewer T cells, impairing immunity and increasing the risk of infection in older adults. In addition, thymic involution increases the risk of cancer and autoimmunity with age. However, research has identified some of the mechanisms of thymic involution and highlighted possible strategies to improve immunity: By activating PPAR-gamma, a protein that regulates fat metabolism, caloric restriction reduced the rate of thymic involution in mice and increased the number and diversity of circulatin... thymic involution immune system thymus autoimmunity

It is a member of the genus Lactobacillus, which comprises most of the bacteria that live on and in the human body. Lactic acid-producing bacteria, such as those in the Lactobacillus genus, are commonly used in probiotic supplements.[ref doi='10.1016/j.tim.2021.01.003'] Furthermore, some online resources provide step-by-step instructions for at-home bulk production of yogurt with L. reuteri enrichment.

Read more[toc position='left'] Background Collagens are major structural proteins in numerous body tissues, including tendons, ligaments, cartilage, skin, blood vessels, muscles, gut tissue, and dentin.[ref doi='10.1101/cshperspect.a004978'] They are the most abundant proteins in the body, comprising 30 percent of the total protein mass. The human body continuously manufactures collagens to maintain tissue structural integrity. However, aging drives a progressive decrease in protein synthesis and reduced capacity to produce new collagen.[ref doi='10.1016/S0047-6374(01)00337-2'] Collagens are also highl... interesting nutrition aging metabolism autoimmunity
Read more[toc position='left'] Background Vitamin C, also known as ascorbic acid, is an essential nutrient, widely recognized for its antioxidant properties. These properties arise from its potent redox potential due to its capacity to donate electrons to oxidized molecules. Even in small quantities vitamin C can protect critical molecules in the body such as proteins, lipids, carbohydrates, and nucleic acids (DNA and RNA) from damage by reactive oxygen species, which are generated during normal metabolism, by active immune cells, and through exposure to toxins and pollutants (e.g., certain chemotherap... cancer nutrition exercise interesting
Read more[toc position='left'] Metformin is a drug commonly used to treat type 2 diabetes. It is the fourth most widely prescribed medication in the United States, with more than 80 million prescriptions for the drug written yearly. Metformin is in a class of drugs called biguanides, which impede liver gluconeogenesis (glucose production in the liver), thereby decreasing glucose uptake in the gut and increasing overall glucose utilization by improving insulin sensitivity in skeletal muscle and fat tissue. Multiple studies demonstrate that metformin reduces fasting blood glucose levels by as much as 3.9... exercise aging diabetes

It is also present to a lesser degree in peanuts and blueberries. Resveratrol protects the plants in which it is present from fungal attack and the damaging effects of ultraviolet radiation. Originally extracted in the 1940s, resveratrol attracted little interest in terms of human health until 1992 when research suggested that it could mediate some of the cardioprotective effects of red wine.[ref doi='10.3390/molecules220202... exercise resveratrol alzheimer's metabolism cardiovascular
Read moreFOXO proteins are members of the FOX family of highly conserved transcriptional regulators. They play essential roles in human lifespan and healthy aging, influenced by environmental and genetic factors. The genetic contribution to lifespan and aging increases with time, suggesting that people who live long lives might carry so-called "protective genes." Run the longevity report to learn more about genetic polymorphisms influencing the expression of FOXO (/genetics) Background FOX proteins are named for a gene found in fruit flies that causes the insects to have forked structures on their head... aging fasting nutrition diet
